I stood up after watching Wimbledon and stretched, suddenly I almost blacked out and landed in a heap on the sofa. It was not a fun experience.
Could this be linked to anaemia/low ferritin? My GP has given up - I was having testing every few months to see what was going on but they couldn't find a reason for it so they stopped checking it. My last ferritin check came back at 9 and the dr actually seemed pleased as it had gone up from 5....
Sigh
